The Ultimate Sin is an album by Ozzy Osbourne. It was released on February 22, 1986, and it was remastered and re-issued on August 22, 1995. This album features guitarist Jake E. Lee (formerly of Mickey Ratt, Rough Cutt and Dio). This is the only Osbourne album to feature bassist Phil Soussan - who wrote the album's U.S. hit single "Shot in the Dark" - and the first to feature the late drummer, Randy Castillo. Lyrics were largely written by long-time Osbourne bass player Bob Daisley, who was also present during the initial writing sessions. Daisley left after having a disagreement with Osbourne, which led to the hiring of Soussan. He was also not credited as a co-writer on the initial 1986 pressing of the album. This was corrected for each pressing after that.
